Xanthophryne Koynayensis
''Xanthophryne koynayensis'' (common names: Humbali Village toad, chrome-yellow toad, Koyna toad) is a species of toad in the family Bufonidae. It is endemic to the Western Ghats of India where it is known from Koyna (including Koyna Wildlife Sanctuary) in the Maharashtra state. Formerly included in the genus '' Bufo'' it has been since made the type species for the genus ''Xanthophryne'' and is a sister species of ''Xanthophryne tigerina ''Xanthophryne tigerina'', sometimes known as the Amboli toad, is a species of toads.

Toad
Toad is a common name for certain frogs, especially of the family Bufonidae, that are characterized by dry, leathery skin, short legs, and large bumps covering the parotoid glands. A distinction between frogs and toads is not made in scientific taxonomy, but is common in popular culture (folk taxonomy), in which toads are associated with drier, rougher skin and more terrestrial habitats. List of toad families In scientific taxonomy, toads include the true toads (Bufonidae) and various other terrestrial or warty-skinned frogs. Non-bufonid "toads" can be found in the families: * Bombinatoridae ( fire-bellied toads and jungle toads) * Calyptocephalellidae (helmeted water toad and false toads) * Discoglossidae ( midwife toads) * Myobatrachidae (Australian toadlets) * Pelobatidae (European spadefoot toad) * Rhinophrynidae ( burrowing toads) * Scaphiopodidae (American spadefoot toads) * Microhylidae ( narrowmouth toads) Biology Usually the largest of the bumps on the skin ...

Koyna Hydroelectric Project
The Koyna Hydroelectric Project is the largest hydroelectric power plant in India, just after Tehri Dam Project. It is a complex project with four dams including the largest dam on the Koyna River, Maharashtra hence the name Koyna Hydroelectric Project. The project site is in Satara district. The Koyana Dam situated near Koyananagar village. On river Koyana. The total capacity of the project is . The project consists of four stages of power generation. All the generators are located in underground powerhouses excavated deep inside the mountains of the Western Ghats. A dam foot powerhouse also contributes to the electricity generation. Due to the project's electricity generating potential the Koyna River is considered as the life line of Maharashtra. The project takes advantage of the height of Western Ghats. Thus a very large hydraulic head is available over a very short distance. History In the early 20th century, there was a survey of the Koyna River as a potential hydro ...

Endemic Fauna Of The Western Ghats
Endemism is the state of a species being found in a single defined geographic location, such as an island, state, nation, country or other defined zone; organisms that are indigenous to a place are not endemic to it if they are also found elsewhere. For example, the Cape sugarbird is found exclusively in southwestern South Africa and is therefore said to be ''endemic'' to that particular part of the world. An endemic species can be also be referred to as an ''endemism'' or in scientific literature as an ''endemite''. For example '' Cytisus aeolicus'' is an endemite of the Italian flora. '' Adzharia renschi'' was once believed to be an endemite of the Caucasus, but it was later discovered to be a non-indigenous species from South America belonging to a different genus. The extreme opposite of an endemic species is one with a cosmopolitan distribution, having a global or widespread range. A rare alternative term for a species that is endemic is "precinctive", which applies to s ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Xanthophryne
''Xanthophryne'' is a small genus of toads in the family Bufonidae. They are endemic to the Western Ghats in Maharashtra, India. Its sister taxon is '' Duttaphrynus''. The name ''Xanthophryne'' is derived from two Greek words, ''xanthos'' meaning yellow and ''phryne'' meaning toad. Description ''Xanthophryne'' are relatively small toads: adult males measure and females in snout–vent length. They have light brown dorsum with a suffusion of dull chrome-yellow; flanks and sides of the abdomen have chrome-yellow patches, sometimes a few continuous bands. The tympanum is indistinct. There is no webbing between the toes and fingers. Eggs are laid in clutches. Species There are two species in this genus: *'' Xanthophryne koynayensis'' (Soman, 1963) *''Xanthophryne tigerina ''Xanthophryne tigerina'', sometimes known as the Amboli toad, is a species of toads.

Habitat Loss
Habitat destruction (also termed habitat loss and habitat reduction) is the process by which a natural habitat becomes incapable of supporting its native species. The organisms that previously inhabited the site are displaced or dead, thereby reducing biodiversity and species abundance. Habitat destruction is the leading cause of biodiversity loss. Fragmentation and loss of habitat have become one of the most important topics of research in ecology as they are major threats to the survival of endangered species. Activities such as harvesting natural resources, industrial production and urbanization are human contributions to habitat destruction. Pressure from agriculture is the principal human cause. Some others include mining, logging, trawling, and urban sprawl. Habitat destruction is currently considered the primary cause of species extinction worldwide. Environmental factors can contribute to habitat destruction more indirectly. Geological processes, climate change, introdu ...

Habitat
In ecology, the term habitat summarises the array of resources, physical and biotic factors that are present in an area, such as to support the survival and reproduction of a particular species. A species habitat can be seen as the physical manifestation of its ecological niche. Thus "habitat" is a species-specific term, fundamentally different from concepts such as environment or vegetation assemblages, for which the term "habitat-type" is more appropriate. The physical factors may include (for example): soil, moisture, range of temperature, and light intensity. Biotic factors will include the availability of food and the presence or absence of predators. Every species has particular habitat requirements, with habitat generalist species able to thrive in a wide array of environmental conditions while habitat specialist species requiring a very limited set of factors to survive. The habitat of a species is not necessarily found in a geographical area, it can be the interior ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Tympanum (anatomy)
The tympanum is an external hearing structure in animals such as mammals, birds, some reptiles, some amphibians and some insects. Using sound, vertebrates and many insects are capable of sensing their prey, identifying and locating their predators, warning other individuals, and locating potential mates and rivals by hearing the intentional or unintentional sounds they make. In general, any animal that reacts to sounds or communicates by means of sound, needs to have an auditory mechanism. This typically consists of a membrane capable of vibration known as the tympanum, an air-filled chamber and sensory organs to detect the auditory stimuli. Anurans In frogs and toads, the tympanum is a large external oval shape membrane made up of nonglandular skin. It is located just behind the eye. It does not process sound waves; it simply transmits them to the inner parts of the amphibian's ear, which is protected from the entry of water and other foreign objects. A frog's ear drum works ...

Species Description
A species description is a formal description of a newly discovered species, usually in the form of a scientific paper. Its purpose is to give a clear description of a new species of organism and explain how it differs from species that have been described previously or are related. In order for species to be validly described, they need to follow guidelines established over time. Zoological naming requires adherence to the ICZN code, plants, the ICN, viruses ICTV, and so on. The species description often contains photographs or other illustrations of type material along with a note on where they are deposited. The publication in which the species is described gives the new species a formal scientific name. Some 1.9 million species have been identified and described, out of some 8.7 million that may actually exist. Millions more have become extinct throughout the existence of life on Earth. Naming process A name of a new species becomes valid (available in zo ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Xanthophryne Tigerina
''Xanthophryne tigerina'', sometimes known as the Amboli toad, is a species of toads. It is endemic to the Western Ghats of India and known only from the vicinity of Amboli in Maharashtra. It was described as a new species in 2009 and placed in a new genus along with its sister species ''Xanthophryne koynayensis''. Description This species is medium-sized for a toad, males are smaller (male snout–vent length , female ), somewhat elongated with a broken canthal ridge. They are yellowish with dark stripes on top and sides of the body and lack webbing between the toes and fingers. Reproduction Breeding takes place in temporary ponds in cavities within lateritic Laterite is both a soil and a rock type rich in iron and aluminium and is commonly considered to have formed in hot and wet tropical areas. Nearly all laterites are of rusty-red coloration, because of high iron oxide content. They develop by ... rock. About 30–35 eggs are laid in a clutch. Habitat and ...

Bufo
''Bufo'' is a genus of true toads in the amphibian family Bufonidae. As traditionally defined, it was a wastebasket genus containing a large number of toads from much of the world, but following taxonomic reviews most of these have been moved to other genera, leaving only seventeen extant (living) species from Europe, northern Africa and Asia in this genus, including the well-known common toad (''B. bufo''). Some of the genera that contain species formerly placed in ''Bufo'' are ''Anaxyrus'' (many North American species), ''Bufotes'' (European green toad and relatives), ''Duttaphrynus'' (many Asian species, including the Asian common toad introduced elsewhere), ''Epidalea'' (natterjack toad) and ''Rhinella'' (many Latin American species, including the cane toad introduced elsewhere). Description True toads have in common stocky figures and short legs, which make them relatively poor jumpers. Their dry skin is thick and "warty". Behind their eyes, ''Bufo'' species have wart-li ...
